COPPER WINDING TEMPERATURE CLASSIFICATION
Insulation systems are arranged in order of their insulation
level and classified by a letter symbol or by a numerical value.
The numerical value relates to the temperature classification
of the insulation system.
The temperature classification indicates the maximum (hotspot) temperature at which the insulation system can be
operated for normal expected service life.
In general, all materials used in a given insulation system
should be rated for temperatures equal to, or exceeding, the
temperature classification of the system.

METALS
Ag (silver)
Fe CrNi 300 Series Stainless Steel (18-8) Austenitic
Silver is a soft, malleable metal with a characteristic sheen.
It has the highest thermal and electrical conductivity of all
metals. Alcon provide shading coil material for stainless steel
valves in silver.
303 Stainless Steel is essentially low-carbon steel to which
chromium has been added. It is the addition of chromium,
in amounts of 18%, that adds strength and gives stainless
steel its unique 'stainless', corrosion-resisting properties. The
corrosion resistance, as well as other useful properties of the
steel, is enhanced by the addition of other elements such as
8% nickel. Alcon provide flange tubes, bodies & springs in
300 series stainless steel.
AI (aluminium)
Derived from the Latin ALUMEN for ALUM (Potassium
aluminium sulphate). A lightweight material that offers high
strength and rigidity along with good corrosion resistance
and heat dissipation. Alcon provide die-cast bodies, solenoid
enclosures and shading coils made from aluminium.
Cu (copper)
Copper is an important engineering material since it is widely
used in its pure state and also in alloys with other metals. In
its pure state it is the most important material in the electrical
industry. It has high electrical conductivity and corrosion
resistance and is easy to fabricate. It has reasonable tensile
strength, controllable annealing properties and general
soldering and joining characteristics. Alcon provide as
standard shading rings produced from Copper.
CU Sn (bronze)
Bronze alloys consist of copper and tin primarily and these
can be known as "tin bronzes". Since phosphorus is usually
added to these alloys as a deoxidising agent during casting,
the tin bronzes are commercially known as "phosphor
bronzes". These alloys possess desirable properties such as
high strength, wear resistance, and good sea water resistance.
Alcon provide bodies from bronze.
316 Stainless Steel
316 Stainless Steel is essentially low-carbon steel to which
chromium has been added. It is the addition of chromium,
in amounts of 18%, that adds strength and gives stainless
steel its unique ‘stainless’, corrosion-resisting properties. The
corrosion resistance, as well as other useful properties of the
steel, is enhanced by the addition of other elements such as
12% nickel. Alcon provide valve bodies flange tubes and coil
enclosures in 316L series stainless steel.
430F & 430FR Magnetic Stainless Steel
Type 430F is a solenoid grade stainless steel that has the
best magnetic properties and lowest residual magnetism.
Type 430FR stainless, used for corrosive service for many
years, also offers improved wear resistance, higher electrical
resistivity and increased hardness. Alcon’s plunger and top
stop materials are produced using the 430F series. Basic
composition 18% chromium, remainder iron.
Cu Zu (brass)
Brass is probably the best known of the “yellow metals” and
it is produced in a wide variety of forms with many different
characteristics and attributes. It is a basic alloy of copper and
zinc and it finds many engineering applications. Alcon provide
forged bodies from brass this forging brass has a composition
of 58% copper, 2% lead and 40% zinc.

MODES OF OPERATION
2/2 N/C Normally Closed
Solenoid Operated
Direct Acting
Solenoid
Pilot Operated
2 way, normally closed, energise to open, on/off operation (de-energise to close), with one inlet and one outlet connection.
There are 2 types of valve operation – Direct Acting and Pilot Operated.
a) Direct Acting – The coil supplies all the power to open the valve and the valve will operate from zero pressure.
b) Pilot Operated – this can either be diaphragm or piston operated. These valves have a pilot hole which is opened/closed
by the coil acting upon a plunger and diaphragm or piston used to control the main Orifice (mm). The operation relies
on the media pressure difference between the inlet and outlet and a minimum operating pressure is required to operate
these valves unless stated as zero.
2/2 N/O Normally Open
Solenoid
Direct Acting
Solenoid
Pilot Operated
2 way, normally open, energise to close, de-energise to open, with one inlet and one outlet connection. Can be either direct acting
or pilot operated.
3/2 N/C Normally Closed
Valve open when energised, closed when de-energised. This valve operates on the same principle as the 2/2 N/C version except the
valve has 3 connections, 2 orices, one permanently open, one permanently closed. The use of these are for operation of actuators
for large valves where single cylinder spring return system is employed.
3/2 N/O Normally Open
Valve open when de-energised, closed when energised.
3/2 UNI Universal
Valve may be used as normally closed, normally open or diversion/selector valve.
5/2
These valves are available in 2 forms;
a) Single Solenoid – 2 position, spool and sleeve type, which is based on an air pilot return mechanism. When de-energised,
the valve allows one inlet and one outlet to be connected, exhausting the other inlet/outlet connection through an exhaust port. On energisation, the action reverses.
b) Dual Solenoid Valves – these spool and sleeve type solenoid valves are momentary contact type. When one coil is energised, one inlet is connected to one outlet, with the other inlet/outlet connection connected to an exhaust port, when
the coil is de-energised and other coil energised, the action is reversed.
These valves are for use on double acting cylinder applications.
40
MODES OF OPERATION
2/2 N/C Normally Closed Pneumatic
2 way, normally closed, pressurise to open, de-pressurise to close with the aid of a return spring, having one inlet and one outlet
connection. Can be direct acting air operated against a return spring. Note: These valves are operated via a 3 way solenoid valve
which is always required.
2/2 N/O Normally Open Pneumatic
2 way, normally open, pressurise to close, de-pressurise to open with the aid of a return spring, having one inlet and one outlet connection. Can be direct acting air operated against a return spring. Note: These valves are operated via a 3 way solenoid valve which
is always required
2/2 N/C Normally Closed Motorised
m
2 way, normally closed, energise to open – (slow opening) de-energise to close – (quick closing) with one inlet and one outlet connection. Motor driven against a return spring.
2/2 N/O Normally Open Motorised
m
2 way, normally open, energise to close – (slow closing) de-energise to open – (quick opening).
2/2 N/C Normally Closed Manual Reset (Solenoid)
These valves operate on the same principle as 2/2 N/C direct acting version except – once the coil is energised the valve will not
open until manually opened by either a lever or push reset device.
2/2 N/C Normally Closed Manual Reset (Motorised)
m
The operation is similar to 2/2 N/C Normally Closed Manual Reset (Solenoid) except, once the motor is energised the valve will not
open till a manual reset/relay button is operated, either remote or integral to the actuator. General use is for both manual reset or
safety systems where knowledge of an electrical failure is required.

SEALING SOLUTIONS
Nitrile (BunaN) (NBR)
* PTFE / TEFLON
Trade Names:
PTFE is a fluorocarbon resin known as a disc sealing material
solution where all other synthetic materials have failed. Rulon
is a form of Teflon having fillers which have been added
for improved mechanical properties. Teflon with fillers are
considered more of a plastic than a resilient-type material.
They are virtually unattacked by any fluid. PTFE provides
sealing solutions for cryogenic and steam applications.
Chemigum Hycar (Zeo (Goodyear)n Chemical), Ny Syn
(Copolymer), Paracril (Uniroyal), Krynac (Polysar), PerNitrilen
(Mobay)
This is the most widely used O-Ring elastomer. It has excellent
resistance to petroleum products. Excellent compression
set, tear and abrasion resistance. Suitable for air, oil, water,
acetylene, kerosene, lime solutions, liquefied petroleum gases
and turpentine.
• Nitrile / BunaN is Alcon’s preferred sealing solution unless
*TEFLON is a registered trademark of Du-Pont.
It must be noted that PTFE sealing will allow slight let-by.
otherwise stated.
• Alcon recommends that Nitrile is used within the
temperature range of -10 °C to +80 °C (14 °F to 176 °F).
• Please note Nitrile is not recommended for highly aromatic
petroleum / gasoline’s or acids.
EPDM (EPR or EPDM)
Excellent resistance to weathering and ozone, water and
steam, with good performance in castor and some phosphate
ester based fluids and poor on petroleum / gasoline. It’s low
and high temperature capabilities are good, having excellent
resistance to set with good resilience, this low compression set
provides a suitable solution for steam sealing. EPDM is suitable
for temperatures above the Nitrile range. Ethylene-propylene
is generally suitable for most photographic solutions as well as
numerous chemical solutions. EPDM has served to replace the
formerly used butyl.
• Alcon recommends that EPDM is used within the
temperature range of -50 °C to +120 °C (-58 °F to +248 °F).
• Please note EPDM should NEVER be used in contact with
mineral based fluids or DI ester based lubricants, due to
excessive swell and deterioration. When lubrication is
required silicone grease or fluids should be used.
*VITON (FPM FLUOROELASTOMER)
It has high temperature capabilities, excellent resistance
to hydraulic oils, petrol and many other chemicals. Viton
O-Rings are used in automobile and other mechanical devices
requiring maximum resistance to elevated temperature and
to many functional fluids. Viton is a fluorocarbon elastomer.
Primarily developed for handling hydrocarbons such as
jet fuels, gasoline’s, solvent, etc., which normally caused
detrimental swelling to NBR. Viton has a high temperature
range similar to ethylene propylene but is more resistant
to “dry heat”. Viton has a rather wide range of chemical
compatibility.
• Alcon recommends that Viton is used within the
temperature range of -20 °C to +150 °C (-4 °F to +302 °F).
*Viton is a registered trademark of Du-Pont
Alcon recommends that PTFE is used within the temperature
range of -200 °C to +180 °C (-328 °F to + 356 °F).
Silicone
This elastomer provides high and low temperature solutions
under certain conditions for numerous applications (it must
be noted that silicone is not suitable for steam applications).
It can handle hydrogen peroxide and some acid solutions.
Silicone’s retention of properties at high temperatures is
superior to other elastic materials.
Alcon recommends that Silicone is used within the
temperature range of -65 °C to +250 °C (-85 °F to +482 °F).
It must be noted that Silicone has poor tensile strength, tear
resistance and abrasion resistance.
Neoprene
Neoprene is commonly used for refrigeration systems sealing
as an external seal. Suitable for alcohol, mild acids, water, air,
ammonia, argon gas and other gases.
Alcon recommends that Neoprene is used within the
temperature range of -20 °C to +90 °C (-4 °F to +194 °F).
Consideration
Although Alcon state a temperature range for it’s elastomers,
limitations are also dependent on their specific function within
the valve. An example of this would be with a diaphragm and
an O-Ring at a low temperature, both will stiffen, however, the
sealing capabilities of the diaphragm will be reduced but the
O-Ring, of similar material, which stiffens at low temperature
may still perform its sealing function. Alcon recommend
that temperatures down to -20 °C (-4 °F) can be considered
tolerable. Elastomers such as low temperature EPDM must
be selected for use below this temperature along with the
application. These can extend the low limit to approximately
minus -40 °C (-40 °F) depending on specific usage. Generally
the upper temperature limit for elastomers is
+100 °C (212 °F). Viton and EPDM can support higher
temperatures up to +150 °C depending upon application.
When applications arise that are below or above the
temperature capabilities of Alcon’s elastomers we can provide
PTFE / PCTFE sealing solutions. These unique chemical-resistant
materials can be used from -200 °C to +180 °C (-328 °F to
+356 °F) when used considering specific design constraints.

Glossary
Glossary of Terms
Flow Data
Water Hammer Protection
Unless otherwise stated, Alcon solenoid valves are catalogued
with respect to flow: Kv m3/hr, or lbs/hr.
It is advised that where high flow rates are encountered, an
accumulator/anti-knock/damper device should be installed
immediately upstream of the solenoid valve.
Individual flow charts are illustrated in the catalogue for each
type of Alcon valve describing the most
common application - air, water, gas or steam.
Where Kv is defined as - The flow of water through a valve at
20º C in m3/hr at a pressure drop of 1bar. The dimensions of
Kv values can be transposed by means of following factors:
Cat No.
Represents the valve in its standard (base) conguration.
Optional specification combinations will modify this number
accordingly - consult manufacturer for ordering part numbers.
Pipe Connection
Cv = 1.16 x Kv
NPT
Kv = 0.853 x Cv
Where Cv is defined as - US Gallons/Minute water with a
pressure drop of 1 PSI
Pressure Ratings
OPD (Operating Pressure Differential Range)
The differential pressure range between the inlet and outlet
ports at which the valve can safely operate.
Catalogue figures represent tests carried out at +/- 10% of
rated voltage in a 20 °C ambient.
P. Max
Temperature Relationship
If a valve is energised for long periods, this causes a
temperature rise in the coil. Applications whereby a high
ambient and high temperature media exist can be reviewed
with the manufacturer to ensure combined temperatures do
not exceed valve operational parameters.
Duty and Protection Class
Alcon Solenoid Valves have coils suitable for continuous duty
(100% ED). The normal voltage tolerance is +/– 10%
Response Time
The maximum pressure the valve can withstand without
causing damage to the components
Zero Pressure Rated (refer to OPD)
When the lower value of OPD is zero, the valve will operate
without pressure differential.
Response times are results based on energising the solenoid
valve on air @ 20 ºC (+68 ºF) until the outlet pressure reaches
a specific percentage of the maximum flow. Response
times will vary depending upon electrical supply, fluid being
processed and differential pressure.
Otherwise this value represents the minimum pressure
differential required to operate the valve.
Mounting
Preferred mounting arrangements are noted below
1) Solenoid vertical and uppermost; valve to be fitted to
horizontal pipe with solenoid vertical.
2) Solenoid horizontal or vertical above pipe; valve suitable
for horizontal or vertical pipe providing solenoid is
horizontal or vertical above the flow line.
• For all liquid applications, the use of a pipeline strainer
provided by others, is recommended.
• All Alcon valves are permanently stamped with directional
flow arrows or port numbering indicating proper flow
direction.
Valves must be installed in accordance with these markings
for proper functionality.
